H.265

H.265, also known as High Eciency Video Coding (HEVC) and MPEG-H Part 2, is a compression

standard. In comparison to H.264, it

oers beer video compression at the same resoluon, frame

rate and image quality.

Prole

This funcon means that under the same bitrate, the more complex the prole is, the higher the

quality of the image is, and the requirement for network bandwidth is also higher.

I-Frame Interval

I-frame interval denes the number of frames between 2 I-frames.

In H.264 and H.265, an I-frame, or intra frame, is a self-contained frame that can be independently

decoded without any reference to other images. An I-frame consumes more bits than other

frames. Thus, video with more I-frames, in other words, smaller I-frame interval, generates more

steady and reliable data bits while requiring more storage space.

SVC

Scalable Video Coding (SVC) is the name for the Annex G extension of the H.264 or H.265 video

compression standard.

The

objecve of the SVC standardizaon has been to enable the encoding of a high-quality video

bitstream that contains one or more subset bitstreams that can themselves be decoded with a

complexity and

reconstrucon quality similar to that achieved using the exisng H.264 or H.265

design with the same quanty of data as in the subset bitstream. The subset bitstream is derived

by dropping packets from the larger bitstream.

SVC enables forward

compability for older hardware: the same bitstream can be consumed by

basic hardware which can only decode a

low-resoluon subset, while more advanced hardware

will be able decode high quality video stream.

10.1.8 Smoothing

It refers to the smoothness of the stream. The higher value of the smoothing is, the beer uency

of the stream will be, though, the video quality may not be so sasfactory. The lower value of the

smoothing is, the higher quality of the stream will be, though it may appear not

uent.
